How can Upgrade MySQL 5.5.40 to MySQL 5.7 - mysql

Question

How can I Upgrade MySQL version
Current MySQL Version: 5.5.40
Target MySQL Version: MySQL 5.7
OS: CentOS release 6.5 (Final)

Answer 1

Probably the quickest way is to dump your older DB version with mysqldump and restore it into 5.7 fresh DB.
How smooth the process goes, depends on how many dropped features in 5.7 you're using in 5.5.
In my case, the only feature, that was dropped in 5.7 was timestamp default '0000-00-00 00:00:00'
The fix for that was to run sed on dump file and replace ''0000-00-00 00:00:00' with CURRENT_TIMESTAMP
sed -i.bu 's/'\''0000-00-00 00:00:00'\''/CURRENT_TIMESTAMP/g' fixed_dumo.sql
Afterthat, the fixed_dump.sql was imported into fresh 5.7 DB and it worked smoothly.
I hope this helps.

Answer 2

The upgrade path is MySQL 5.5 -> MySQL 5.6 -> MySQL 5.7
See https://dev.mysql.com/doc/refman/5.7/en/upgrading.html

Answer 3

step 1 : take a backup
mysqldump --lock-all-tables -u root -p --all-databases > dump.sql
step 2 : remove old mysql
sudo apt-get remove mysql-server
sudo apt-get autoremove
step 3 : install new version of mysql 5.6
sudo apt-get install mysql-client-5.6 mysql-client-core-5.6
sudo apt-get install mysql-server-5.6
for 5.7
wget http://dev.mysql.com/get/mysql-apt-config_0.6.0-1_all.deb
sudo dpkg -i mysql-apt-config_0.6.0-1_all.deb
sudo apt-get update
sudo apt-get install mysql-server
step 4 : edit your data to address differences between versions (5.5 and 5.7)
If you have create table and timestamp(6) column is used than default values should be changed from CURRENT_TIMESTAMP to CURRENT_TIMESTAMP(6)
`event_time` timestamp(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6),
step 5 : restore your data
mysql -u root -p < dump.sql
step 6 : Try to add a new db user. To validate and fix issues introduced from import of system tables like users (ERROR 1805 (HY000): Column count of mysql.user is wrong.)
mysql_upgrade -u root -p

Answer 4

I might be late to the party, but easy and fast solution without or minimal downtime could be AWS Database-Migration-Service, which can be used to upgrade your database to a different version as well as to some other server or RDS.
I have tried this and converted MySQL5.5 to MySQL5.7 on production without any downtime.
Here is a demo for the same - How To Migrate MySQL5.5 to MySQL5.7
Steps:
Set your current MySQL as master
Create a new instance/server with MySQL5.7 on it with required users
Got to AWS DatabaseMigrationService (DMS) and create a Replication
instance
After creating replication instance it will ask to fill up connection
detail to source(MySQL5.5) and target(MySQL5.7) databases.
Create task in DMS, which will be the logic on what basis you want to
migrate the data (particular database or particular table)
Start the task
When task is completed and data is in sync, just switch the DNS entry
pointing to MySQL5.5 to MySQL5.7

Answer 5

Yes. From a "logical upgrade" you can migrate from 5.5 for 5.7. This way: 5.5 -> 5.6 -> 5.7, is necessary only for "in place" upgrade, with data folder.

Answer 6

Fallow Simple Steps for Upgrade Mysql Version 5.5 to 5.7 .
wget http://dev.mysql.com/get/mysql-apt-config_0.8.0-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.0-1_all.deb
sudo apt-get update
sudo apt-get install mysql-server

Answer 7

After a bunch of failed attempts I have concluded it down to:
To upgrade from 5.5, go to 5.6 first and then to 5.7
Save the datafolders and install a fresh installation of 5.7
Both need the apt-config mentioned in all above comments.
The kicker is to run sudo apt install mysql-**community**-server

Answer 8

in Mysql,
step 1: fetch version,
wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
step 2:
rpm -ivh mysql57-community-release-el7-9.noarch.rpm
step 3:
check available mysql repo,
yum repolist all | grep mysql
will get something like below,
mysql55-community/x86_64 MySQL 5.5 Community Server disabled
mysql55-community-source MySQL 5.5 Community Server - S disabled
mysql56-community/x86_64 MySQL 5.6 Community Server disabled
mysql56-community-source MySQL 5.6 Community Server - S disabled
mysql57-community/x86_64 MySQL 5.7 Community Server enabled: 384
mysql57-community-source MySQL 5.7 Community Server - S disabled
Its preferred to upgrade one by one,
so first upgrade into mysql 5.5 into mysql5.6
step 4: first enable to mysql 5.6 and disable mysql 5.5 and 5.7
sudo yum-config-manager --enable mysql56-community
sudo yum-config-manager --disable mysql55-community
sudo yum-config-manager --disable mysql57-community
step 5: before upgrade stop service,
sudo systemctl stop mysql
step 6: Lets ready to upgrade,
yum update
you are successfully upgrade into mysql5.6
now repeat step 4 to 6 to upgrade into 5.7
sudo yum-config-manager --disable mysql56-community
sudo yum-config-manager --enable mysql57-community
and then
yum update
mysql --version
successfully upgraded into mysql 5.7 dont forgot restart service,
systemctl start mysql

Answer 9

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mysql-server-5.6
